Texas Instruments · Voltage Reference · SOT-23
ATL431AQDBZR from Texas Instruments, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CATHODE | bidirectional | Parallel current/voltage input; recommended cathode voltage is up to 36 V (Vref to 36 V) and cathode current 35 µA to 100 mA, with absolute maximums of 40 V and -100 mA to 150 mA. |
| 2 | REF | input | Reference input that regulates to the internal 2.5 V reference relative to ANODE; it must not float and needs Iref of at least 0.1 µA, with an absolute maximum reference input current of 10 mA. |
| 3 | ANODE | passive | Common pin, normally grounded, to which all voltages are referenced per the absolute maximum ratings note; the datasheet lists it as an output (O) type. |
